The photo isn’t really that great and it appeared to me the whole cap was frosted. I’m not really sure now.

I have some concern about naming immature material from Utah A. aprica. (EDITED)

There is no typical (of aprica) yellow-orange cap color exposed at all. The exposed pileipellis looks a faintly yellowish cream. Based on geography, cap color, and lack of frosted areas between warts (in the top two images), I think this is unlikely to be aprica.

I’d suggest just going with Amanita section Amanita as a good possibility.

Very best,
